He continued: "My family and I are grateful for the outpouring of love and support. We ask that our sincere request for privacy be honored during this time.”

The former marine biology teacher channelled his love of the ocean to launch SpongeBob in 1999.

The cartoon became a runaway success and spawned The SpongeBob SquarePants Movie in 2004, which Stephen directed.
